ABSTRACT:
An electrolytic method for making tin (II) sulfate wherein tin is anodically dissolved in a sulfuric acid solution and wherein the anode space is separated from the cathode space by a diaphragm, the diaphragm being composed of an inorganic, ceramic material which has been densified by sintering at above 1,000.degree. C.
As a result of this process, tin (II) sulfate solutions can be obtained which have a very low content of tin (IV) compounds and from which a highly pure bivalent tin sulfate can be recovered.
